An amplifier of integrated circuit construction for operating on input voltages less than 10 mV has a signal amplifier which is associated with a regulation loop for regulating out static offset voltages and slow offset voltage drifts. The output of the signal amplifier (1) is connected to the input of a switching amplifier (2) and to the output of a third amplifier (4). At the output of the switching amplifier, which is connected to the input of the third amplifier (4), a capacitor (3) is connected which has its other terminal connected to ground. An output coupling amplifier (5) can aid the switching amplifier (2) in its switching function.
